Description

The invention relates to a technology for preparing a multicomponent suspension based on fuel oil and / or coal, and water, and can be used in the energy industry, agriculture, and medicine.

A known method of processing components by separating them into light and heavy fractions, reforming the light fraction at elevated temperature and pressure, extracting products to produce aromatic hydrocarbons and raffinate, mixing the raffinate and heavy fraction of secondary reforming the mixture at elevated temperature and pressure. (RU 2080353, class C10G 59/06, 05.27.1997).

However, in this method, an enhanced cracking reaction occurs, due to the low selectivity of the conversion of hydrocarbons included in the raffinate, as well as the accumulation of difficultly reformed hydrocarbons in the circulating stream.

A known method of processing and separation of a multicomponent mixture, mainly a hydrocarbon composition, comprising supplying a liquid product under vacuum with separation into a vapor-gas and liquid phases, pumping gases and vapors from it with a jet vacuum-generating device, followed by separating it by condensation into a liquid and non-condensed vapor-gas fraction with removal the latter for disposal (application WO No. 96/05900, CL B01D 3/10, C10G 7/06, 1996).

The disadvantage of this method is the use of condensate from the separator as the active liquid of the jet vacuum-generating device, which leads to its multiple accumulation by contaminants, which significantly degrades the quality of the finished product and leads to additional costs for its post-treatment.

The closest to the method of processing hydrocarbon mixtures according to the technical essence of the invention is a method for distillation of hydrocarbon mixtures (crude oil, gasoline, etc.), which includes supplying the original liquid mixture to a nozzle with a liquid-gas-liquid outflow into the chamber under pressure using a pump (RU 2087178, C. C10G 7/06, 08/20/1997).

A technical solution is known for processing a multicomponent mixture by separating it into light and heavy fractions, reforming the light fraction at elevated temperature and pressure, extracting products to produce aromatic hydrocarbons and raffinate, mixing the raffinate and heavy fraction of secondary reforming of the mixture at elevated temperature and pressure to obtain high octane component, while a fraction boiling from 90 to 103 degrees C is preliminarily isolated from the raffinate and mixed with a heavy fraction (RU 2080353, class C10G 59/06 , 05.27.1997).

Closest to the installation for processing multicomponent liquid mixtures according to the technical essence of the invention is a plant for the distillation of multicomponent organic mixtures, including a feed pump, vacuum-generating devices, a horizontal chamber, pressure and drain lines and control devices (RU 2166528, class C10G 7/06, (29.06 .1999).

The disadvantage of the described device is the insufficiently high efficiency of its operation, associated with high material consumption and excessive energy consumption, and in the design, with the complexity of the layout.

The technical task of the proposed method for the preparation of a multicomponent suspension based on fuel oil and / or coal, and water is to expand the functionality through the use of a multicomponent suspension in various industries. The technical problem is ensured by the fact that the method of preparing a multicomponent suspension based on fuel oil and / or coal and water is characterized in that at the first stage of preparation, fuel oil and / or coal with natural moisture and particle sizes are loaded into a grinding device made in the form of a hollow volumetric housing with a multistage rotor coaxially mounted in it, where water is supplied simultaneously with the loading of fuel oil and / or coal, while the components are supplied under pressure up to 60 atm. and processed at temperatures up to 100 degrees C, and the final processing is carried out in an additional chamber by turbulent-cavitating action with simultaneous dispersion and magnetization of the suspension components.

When preparing a suspension based on fuel oil and water, the ratio of water to fuel oil is in the range of 20:80.

When preparing a suspension based on coal and water, the ratio of water to coal lies in the range of 20:80.

When preparing a suspension based on three components - fuel oil, coal and water, the ratio of water to fuel oil and coal lies within 20: (40 + 40).

In the case of preparing a multicomponent suspension based only on fuel oil and water, the components are passed through a volumetric filter and sent to the unit for magnetization, mixing and dispersion.

In the case of the preparation of a multicomponent suspension based on only coal and water, the components are sent directly, bypassing the volumetric filter, into a plant for grinding dispersion and magnetization.

In the case of the preparation of fuel oil, coal and water components, the components are loaded directly into the installation for grinding, magnetization and dispersion by turbulent-cavitating action under pressure up to 60 atm. and processed at temperatures up to 100 degrees C.

After final processing of the components in the additional chamber by a turbulent-cavitating action with simultaneous dispersion and magnetization of the components, they are unloaded from the magnetic chamber through the outlet pipe of the finished product connected to it.
